precreate arbitrary code execution

[baszalmstra]

While porting the code to Rust I came across the precreate field. If I read the code correctly this allows executing arbitrary code at installation time which is a security risk. I am on personal vendetta against this in conda (link scripts too). 😺

I could not find a use of this in any conda-forge feedstock so I was wondering what the usecase for this would be?

Would it be possible to do achieve the same result without executing arbitrary code?
